A mixed-use office building taking shape in North Portland features a unique shape reminiscent of the iconic Flatiron Building in New York City. Flatiron PDX will consist of a ground-floor retail space and open office space on the upper floors. Works Progress Architecture is the designer of the six-story structure, which Abbott Construction is building on a triangular lot at North Mississippi Avenue and Cook Street for developer Brandon Brown of Southern Miss LLC.

The building’s first two floors are post-tensioned concrete slabs, with the upper four floors constructed of cross-laminated timber supported by glue-laminated beams. The CLT floors, sourced from Structurlam in British Columbia, Canada, will be topped with a three-inch slab of poured-in-place concrete. Five concrete shear walls will provide lateral stiffness.

The building’s upper four office floors will each have a footprint of around 4,400 square feet, while the second-floor office space will measure around 2,400 square feet. The building also will feature a small parking garage at a half-floor below grade.

The 12-month core-and-shell project is slated for completion in March 2018.
